SC 350: The most common ID sensor dirty: Clean the ID sensor

This code can be reset be turning off the main power (orange rocker switch) for about 10-seconds and then turning the machine back on. If the error comes back up, then there is a definite problem with the machine and it should be looked at by a train service technician.

I answered this post here already:

There's nothing more that can be done.

Probably just a dirty "ID sensor". If you remove the drum (carefully) and set aside. Open the right cover, and towards the back of the machine above where the drum sits there is a small LED sensor mounted pointing down toward where the drum sits. Clean this with a tissue, put back drum and try.
If this fails, then the sensor is bad (or broken wire), or there is a circuit board problem (serious). Either IOB board or High voltage board.

Hope this helps.

SC101 Scan Lamp Error
SC350 ID sensor pattern test error

Your scanner should be checked by a technician to determine what is causing the error. There isn't any calibration or troubleshooting that can be done unless you have scanner parts.
